call your insurance agent and smile.........
if a tree in your yard blows into your neighbors yard and even flatens his home, its his problem./
it becomes his property as it crosses the property line
I had a tree limb do that and hit my neighbors car, he was out of luck and had zero comprehensive insurance. it was a junk car, right after that the engine blew and it went to the junk yard...
the only exception......
if your informed the tree is a hazard. someone comes and says hey your tree is dying, it could blow over and flatten my home...
if it does your on the hook........
now cooperating with your neighbor is always best, neighborhood wars are bad.
but call your insurance and ask, then tell your neighbor its not your problem.
then offer to help him clean up.......... and perhaps trim the overhanging branches.
but those are his responsiblity too.
when a tree overhangs a property line, the property owner it overhangs is responsible, and can prune as they wish,
